Connecting to a video player, etc.
1.  Connect one end of the optional video cable to the VIDEO 
IN terminal of the projector. 
2.  Connect the other end of the video cable to the video 
output terminal of the video equipment. 
•  Also read the instruction manual of the equipment to be connected. 
•  Contact your dealer for details of connection.
When a TV tuner or VCR is connected:
When you use this projector with a TV tuner or VCR connected, no image may appear or a message of NO SIGNAL 
may appear on the screen when you change the channel via any channel that is not being received. In such a case, 
set the channels of the TV tuner or VCR again. To avoid such symptom, use the TV tuner or VCR with its channel skip 
function (that is a function not to display channels that are not being received) enabled. 
Connecting to a DVD player
To connect this projector to video equipment that has component video output terminals, such as a DVD player, use 
the COMPONENT terminals. When the video equipment is equipped with the S-video 
output terminal, make the connection as follows. 
1.  Connect one end of the optional S-video cable to the 
S-VIDEO IN terminal of the projector. 
2.  Connect the other end of the S-video cable to the S-video 
output terminal of the video equipment.  
•  Images may not be projected correctly depending on the type of the DVD player you use. 
•  Though it may take some time before an image is displayed on the screen depending on the type of the input 
signal, such symptom is not a malfunction.

Connecting to video equipment having a DVI-D terminal
You can project high-quality images by connecting the DVI-D terminal of this projector to video equipment having a 
DVI-D output terminal. In addition, this projector supports HDCP and is able to receive encrypted digital video data 
that are output from DVD players. 
•  For connection to the DVI-D IN terminal, use a commercially available DVI cable. 
•  Select DVI as the input source. 
•  Only RGB signals are supported. Component video signals are not supported. 
•  HDCP (High-bandwidth Digital Content Protection), developed by Intel Corporation, is a method to encrypt digital 
video data for the purpose of copy protection. 
•  When DVI is selected as the input source, setting of COLOR, TINT, FINE SYNC., TRACKING and HOLD is 
unavailable. 
When you connect this projector and a DVI-Digital device (such as a DVD player) via the DVI-D (HDCP) 
terminal, black color may appear dark and deep, depending on the type of the connected device. 
•  This depends on the black level setting of the connected device. There are two kinds of methods to digitally 
transfer image data, in which different black level settings are employed respectively. Therefore, the specifi cations 
of the signals output from DVD players differ, depending on the type of the digital data transfer method they use. 
•  Some DVD players are provided with a function to switch the methods to output DVI-Digital signals. When your 
DVD player is provided with such function, set it as follows.
  EXPAND or ENHANCED →
 NORMAL
•  See the users guide of your DVD player for details. 
•  When your digital device does not have such function, adjust the BRIGHTNESS to +16 and CONTRAST to -16 
in the IMAGE menu of this projector, or adjust the black color by viewing the image.
B. Plugging in the power cord
1  Plug the attached power cord into the power cord inlet of 
this projector.
2  Plug the other end of the power cord into a power outlet.
•  The power cords for use in the U.S. and Europe are included with this projector. Use the appropriate one for your 
country. 
•  This projector uses the power plug of three-pin grounding type. Do not take away the grounding pin from the 
power plug. If the power plug doesn’t fi t your wall outlet, ask an electrician to change the wall outlet. 
•  The provided power cord for the U.S. is rated at 120 V. Never connect this cord to any outlet or power supply 
using other voltages or frequencies than rated. If you use a power supply using other voltage than rated, prepare 
an appropriate power cord separately.

ENGLISHC. Projecting images
Preparation:
•  Remove the lens cap.
•  Turn on the power of the connected video equipment. 
1. Confi rm the POWER indicator lights up red. 
•  If the projector was turned off before the lamp was cooled down suffi ciently last time, the fan may start rotating 
and the POWER button may not work after the power cord is plugged. (The STATUS indicator blinks green.) 
After the fan stops rotating, press the POWER button to turn back on the POWER indicator. 
2.  Press the POWER button on the projector or ON ( I ) button on the remote control. 
•  It may take about one minute for the lamp to light up. 
•  The lamp fails to light up on rare occasions. In such a case, wait for a few minutes and then try again. 
•  Do not cover the lens with the lens cap while the lamp is on. Do not strip off the aluminium sheet inside the 
lens cap.
•  The STANDARD lamp mode is activated by default whenever the projector is turned on. When the LOW lamp 
mode has been chosen, the default STANDARD lamp mode is switched to the LOW lamp mode in 1 minute.
3.  Select an input source. 
•  Press the VIDEO button on the projector or the VIDEO, S-VIDEO or COMPONENT button on the remote control 
that is corresponding to the terminal in use. 
•  The input source is switched between VIDEO, S-VIDEO and COMPONENT at every press of the VIDEO button 
on the projector. 
•  Though it may take some time before an image is displayed on the screen depending on the type of the input 
signal, such symptom is not a malfunction. 
•  Some images become easier to view when the setting of aspect ratio is changed. (See Page 17.)
4.  Adjust the position of the projector to keep an appropriate projection distance with which images are projected in 
their specifi ed sizes. 
5.  Adjust the position of the projector so that the projector and the screen are perpendicular to each other. (See Page 
10.) 
•  When the projector cannot be positioned perpendicularly to the screen, adjust the projection angle. (See Page 
10.)
6.  Adjust the size of the projected image by turning the ZOOM ring. 
7.  Adjust the focus by turning the FOCUS ring. 
Repeat steps 4 to 7, if necessary.
